Cancer is the deadliest disease of the century. Advances in medicine and years of research have led to the development of a range of treatments for cancer. Chemotherapy, surgery, proton therapy, cryosurgery, radiotherapy, etc. are few treatments. Radiation occurs in approximately 50-60% of tumors patients.This method of cancer treatment is applied to almost any type of cancer, including breast cancer,pancreas, prostate, uterus, lung, leukemia, cancer that affects the lymphatic system, soft tissue sarcomas, etc.
Radiation therapy is a targeted therapy of cancer who seek to destroy. This treatment impairs the ability of cancer cells to replicate and spread the cancer. There are several advanced methods of radiotherapy such as proton therapy, stereo tactic radio surgery, etc.
What is radiotherapytreatment?
Radiation therapy can be defined as a cell targeted therapy using ionizing radiation to kill cancer cells. It can damage the genetic heritage of the cells, which in turn determines the cessation of growth and replication of these cells. This radiation can damage normal cells nearby. But most normal cells can recover from this. maximum destruction of tumor cells is the goal of treatment. Irradiation is used to destroy cancercompletely or to reduce the tumor to relieve symptoms.
Radiotherapy or surgery can be used alone or in combination with chemotherapy. This is done mainly for the success of the treatment. There are cases where irradiation is used as symptomatic treatment or palliative care to relieve symptoms such as pain and the patient's condition has improved.
Several methods of Radiotherapy
There are basically two types of radiation-The external radiotherapy and internal radiotherapy. The effectiveness of external beam radiation therapy can be achieved by using sophisticated techniques such as three-dimensional radiation therapy-based intensity modulated radiation therapy (IMRT) and proton irradiation (PBRT). The stereo tactic radiotherapy is a method used in the treatment of brain tumors. It can be done in three ways, Linac-based stereo tactic radio surgery, the use of heavy loads or protons and helium ionsThe Gamma Knife technology. Brachytherapy is a more advanced method.
The effectiveness of radiation therapy of various cancers
Radiation therapy has prolonged the survival of cancer patients. Like any other treatment cells respond differently to this treatment. Radiosensitivity shows the response of tumor cells. Dose of radiation is the term used to describe the amount of radiation absorbed by cancer cells. The currentused unit of radiation dose Gray (Gy).
The tumor cells highly sensitive and cancers of the blood and the germ cells are rapidly destroyed by small doses of radiation. Moderately sensitive cells such as cancer cells need a high dose of radiation. There are also radio-resistant cells. Melanoma and renal cell carcinoma are good examples. In these cases a higher dose of radiation is preferred. densitivity healing of tumors differother.Leukaemia can not be cured if the cancer cells spread through the body. Lymphoma can be cured if it is directed to a specific area. The radio reactive Turner are usually treated with curative doses of radiotherapy.
Size Matters in the treatment of cancer. Small tumors respond better than large tumors. There are different methods adopted to cancel this effect. Therapy before surgical resection is a common method. 'S view, widespread in human milkcancer treatment. With neoadjuvant chemotherapy before radical radiotherapy is another method. Several drugs such as cetuximab, cisplatin, etc. are given before this radiotherapy.All radiopharmaceuticals tion Sensi.
